You can use good old fashioned Milsurp if you are just plinking. If you want to do some hunting or such, Hornady, Federal and probably some others, produce 30-06 rounds specifically for the M-1 Garand with lower pressures than modern rounds. They are specifically marketed for M-1 use.

Here are a couple cheaper options. Most 30-06 produced today is for hunters or accuracy geeks, not much 'plinking' ammo in 30-06 except milsurp and it's still outrageously expensive compared to 5.56 or 7.62x39.
